Pipe Hole Cutters for Pipeline Tapping Applications

The main types of pipe hole cutters are HSS (high speed steel) tipped, carbide tipped, and diamond segment cutters. HSS tipped cutters suit steel lines, carbide tipped cutters work on most pipeline materials, and diamond segment cutters are designed for concrete lined pipes, each featuring a deep tooth profile to reduce material buildup.

For a 2 inch pipe tap, a holesaw sized slightly larger than the outer diameter of the pipe is typically required to accommodate the cutting shell and pilot drill. Sizing varies by tapping machine and adapter, so it's best to consult technical support to match the correct cutter and boring bar to your specific tapping machine and pipe schedule.

Hot tapping is the process of cutting into a pressurized, in-service pipeline to add a branch connection or valve without shutting down flow. A pipe hole cutter, mounted to a tapping machine, cuts through the pipe wall to create the opening while the coupon is retained by the cutter, allowing safe, uninterrupted service.

Carbide tipped and diamond segment cutters are available up to 72 inches in diameter, while HSS tipped cutters are available up to 48 inches. Cutter sizing is matched to the tapping machine and pipeline diameter, and custom sizes can be manufactured to fit specific project requirements.

Yes, all cutter types including HSS tipped, carbide tipped, and diamond segment cutters can be custom manufactured to adapt to any tapping machine, regardless of brand. This flexibility allows pipeline service companies to standardize on preferred cutter styles across different equipment.

HSS tipped cutters are designed for steel lines, carbide tipped cutters work across most pipeline materials including ductile iron, PVC, and steel, and diamond segment cutters are engineered specifically for concrete lined pipes, ensuring the right cutter is available for nearly any pipeline material encountered in the field.
